Asphalt is a waterproof, moisture-proof and anti-corrosive organic cementing material, mainly used in industries such as coatings, plastics, rubber, etc. and for paving roads. At different temperatures, asphalt exists in different physical states. Specifically as follows: 1. High-temperature state: When asphalt is heated to about 150 °C, it will present a liquid state; 2. Normal-temperature state: When the temperature of asphalt drops below -15 °C, asphalt will present a solid state. And when the temperature rises to about 5 °C, asphalt will present a state between solid and liquid.
